| Outline of Final Research Achievements |
Aggressive periodontitis (AgP) has its onset in juvenile and is characterized by severe and rapid periodontal tissue destruction. AgP has been reported in relation to genetic background. However, to date, causative gene has not been identified. In this study, we analyzed a Japanese AgP family with autosomal dominant hereditary by using linkage analysis and exome sequencing. To understanding this pathology, we used the genome-editing tool transcription activator-like effector nuclease (TALEN) and generated knock-in (KI) mice. The aimed missense mutation and frameshift mutations were obtained. Alveolar bone loss by ligatured induced inflammation was significantly increased in KI mice and KO mice compared to wild type (WT) mice. Our findings will be useful for understandings the different facets of host-pathogen interactions in AgP and developing new specific therapy for AgP.
